Make the CoglContext structure a bit more maintainable

Browse Source 
This moves most of cogl-context.{c.h} to cogl/common with some driver
specific members now living in a CoglContextDriver struct.  Driver specific
context initialization and typedefs now live in
cogl/{gl,gles}/cogl-context-driver.{c,h}

Driver specific members can be found under ctx->drv.stuff
